North Carolina Assistive Technology Program
Ja MedlicottAT Consultant
NCATP 2005 Expo
3 Continuum Sessions
Identification: Basic Computer Access AssessmentFrom 8:30-9:30
Application: AT for Computer Access From 10:00-11:00
Integration: Multiple Technologies Working in Concert From 12:30-3:00
Sessions Break DownIdentification: Basic Computer Access Assessment This session will break down the basic domains of computer access. The importance
of focusing on a specific desired computer task when assessing will be examined. Compass computer access assessment software from Koester Performance Research will be presented.
Application: AT for Computer Access This session will present software and hardware applications for computer access.
Mouse and keyboards options along with desktop/text enlargement, audio text /navigation, and text/command entry software will be presented.
Integration: Multiple Technologies Working in Concert This session will integrate all previous discussed software and peripherals in sessions
1 and session 2 into a” working concert” Mounting devices will be review for switch access and discussed peripherals. Eye-tracking technology from Eye Response Technologies will also be presented by Mel Ellison from Learning Resources Assistive Technologies.
Identification
Basic Computer Access Assessment
First must review
“Computer Access”
Session 1
The Basics ofComputer Access
Physical location of the computer
The computer skill level of the individual
To use a computer you need output / input(Need one or more Peripheral)
Know what you want to do on the computer (In measurable and observable terms)
Session 1
Physical Computer Location
Is the computer accessible from a wheelchair?
Is the computer table adjustable?
Is the “CPU” the box on the floor?
Session 1
Adjustable Computer Table
A person’s positional needs in computer access should to be reviewed by a PT or OT
Assistive technology can help position computer peripheralswith mounts and adjustable tables and chairs
Session 1
The Basics ofComputer Access
Physical location of the computer
The computer skill level of the individual
To use a computer you need output / input(Need one or more Peripheral)
Know what you want to do on the computer (In measurable and observable terms)
Session 1
Computer Skill Level
AT can not providecomputer skills!
Desktop / Tool BarMouse Cursor /PointerKeyboard Cursor

Session 1
The Basics ofComputer Access
Physical location of the computer
The computer skill level of the individual
To use a computer you need output / input(Need one or more Peripheral)
Know what you want to do on the computer (In measurable and observable terms)
Session 1
Output
For an individual to work with acomputer they need to “see” or “hear”
the desktop or computer screen.
Session 1
Ways to help to see
(Get information from the monitor)
Screen Resolution Increase Icon Size / Font Appearance Increase Cursor Size Magnification
Session 1
Remember there are two types of Output
For an individual to work with a
computer they need to “see” or “hear”
the desktop or computer screen.
Session 1
Ways to “Hear” Monitor
To help an individual hear a representation of the desktop or to navigate around it.

Session 1
Input
Once one has received information from the computer they need to be able to
respond
Point
Select
Enter Text
Session 1
How do we Point?
A Mouse
Session 1
Pointing with a Mouse
In computer access you need to think of moving the mouse cursor not the mouse!
Session 1
Mouse Cursor
Think of your mouse cursor as your Pointer!
Session 1
Other ways to Point
Options for individuals that can not point with a mouse
Mouse Scanning Software
ScanBuddy

Gus Scanning Cursorhttp://www.gusinc.com/scancur.html
Can also use Pointing Devices
These are hardware devices

Session 1
Input
Once one has received information from the computer they need to be able to
respond.
Point
Select

Session 1
How do we Select?
By Clicking!
Session 1
Mouse Clicking
A mouse click is nothing more than a switch
You are pushing or activating a button to make a selection
Session 1
Select
To make a selection you point then
Click a mouse
Push a button/switch
Dwell
Instead of using a mouse click for a selection you can use a variety of switches
Session 1
Dwell?
Dwell is automatic clicking
(or selecting)
Software that allows you to aim and (dwell over) a target and select without clicking your
mouse or switch
Session 1
Dwelling Example Session 1

Session 1
Keyboard Input
A keyboard is a device that allows one to place text into a target.
This is called the keyboard cursor
Pointer or mouse cursor
Session 1
Keyboard Types
External KeyboardOn Screen Keyboards
Session 1
On Screen KeyboardAccess Methods
On screen keyboards can be access in three ways
Mouse Point and Click
Dwelling
Scanning
Session 1
Scanning Method Session 1
Other Text Entry Methods
Voice to Text Software
“Voice Recognition allows a user to use his/her voice as an input device. Voice recognition may be used to dictate text into the computer or to give commands to the computer (such as opening application programs, pulling down menus, or saving work)”
Session 1
Dasher
Is a pointing (zooming) text entry interface
Software that allows you to point to letters to type.
Session 1
The Basics ofComputer Access
Physical location of the computer
The computer skill level of the individual
To use a computer you need output / input(Need one or more Peripheral)
Know what you want to do on the computer (In measurable and observable terms)
Session 1
What tasks do they want to accomplish?
Get on Internet, Read Email, Do my job,
Do Homework, Research, Learn, Math,
Communicate, Play Games, Make Lists,
Banking, Get Pictures, Draw, Make Movies,
Design, Create, Listen to Music,
Increase Computer Skills.
Session 1
Must be Specific of the Task
If someone says “I have trouble using the mouse”
Ask in moving the cursor or clicking?
If someone says “I have trouble typing”
Ask can you not use the keyboard at all or are you not satisfied with words per minute?
Session 1
Get very specific!
Example: TypingWhat are you typing?
Short emails Data entry Long paragraphs
In what program/s? Outlook Excel Word
Session 1
What drives AT?
Assistive technology is driven by the Task not the disability!
A person’s disability does help steer a device or program but is not the driving force.
